Find any airport by its IATA or ICAO code, name or city: codes, location, elevation and scheduled service.
How to use
- Type a three-letter code from a boarding pass or luggage tag (HEL), a four-letter code from a flight plan or weather report (EFHK), or an airport's name or city.
- Narrow the list to one kind of facility if you like, such as large airports or heliports.
- Select a row to see its codes, country, elevation and coordinates, and copy what you need.

How it works
Most airports have two codes. The three-letter IATA code (HEL) is the one on tickets, timetables and baggage tags; the International Air Transport Association assigns it to airports with passenger or cargo service. The four-letter ICAO location indicator (EFHK) is the one pilots, air traffic control and weather reports use; the International Civil Aviation Organization publishes them in its Doc 7910. Small airfields and heliports often have only an ICAO-style code.
ICAO codes are built by region: the first letter is a part of the world and the second usually a country. E is northern Europe, and EF is Finland, so EFHK is Helsinki-Vantaa and EFTP is Tampere-Pirkkala; K is the contiguous United States (KJFK), C is Canada and Y is Australia. IATA codes have no such pattern, so HEL, LHR and YVR must be learnt or looked up.
The list comes from OurAirports, a public-domain database kept by volunteers, and holds about 20,000 open airports, airfields and heliports. Elevation is the height of the airport's reference point above mean sea level, shown in feet as in aviation (1 ft = 0.3048 m). The data is for travel and learning, not for flight planning or navigation: pilots use the official aeronautical information publication of each country.
Frequently asked questions
What is the difference between IATA and ICAO codes?
IATA codes have three letters and are used by airlines and passengers (HEL). ICAO codes have four letters and are used in aviation operations, flight plans and weather reports (EFHK). Most large airports have both.
Why do the ICAO codes of Finnish airports start with EF?
ICAO codes start with a region letter and usually a country letter. E covers northern Europe and EF is Finland, so every Finnish airfield's code starts with EF. Sweden is ES, Norway EN and Estonia EE.
Why can't I find a small airfield's IATA code?
Many airfields have none: IATA assigns codes mainly to airports with commercial service. Search by the four-letter ICAO code or the name instead.
Which airport is LHR?
London Heathrow, ICAO code EGLL. London has several airports: Gatwick is LGW, Stansted STN and City LCY.
Can I use this for flight planning?
No. The data is from a volunteer database and may be out of date. Use the official aeronautical information publication (AIP) and charts for anything that matters for a flight.
